Fin Rot

Fin Rot

Fin rot is most likely not going to occur in well kept aquariums. Fin
rot is caused by an excess amount of bacteria in the aquarium that
should have normally been taken care of with weekly water changes.
Symptoms are violent on the fish, including blood streaked and ragged
fins and will eventually eat away the whole fin of the sick fish.
Treatment can be found most local pet stores.

Signs

Behavioral

Difficulty swimming

Fish tends to dart around aquarium

Immediate Actions

Do a water change and continue doing them frequently (twice a week).

Many fish stores offer treatment for this disease at a cheap cost of around $8 CAD. When treating the aquarium (the whole aquarium must be treated as this disease is highly contagious) make sure to follow the manufactures directions.

Prevention:

As always, maintain good water quality

Feed the fish in smaller quantities as to not allow fish food to accumulate in the aquarium
